Setting the quality for ffmpeg command?

Question

What do I have to add to this command:

cat *.jpg | ffmpeg -f image2pipe -r 10 -vcodec mjpeg -i - out7.webm

to get the best available quality?

Answer 1

Try adding the switch "-qscale x".

The lower your x, the better is the quality (range 2 to 32, fractions allowed). It should work.
